Well, that's precisely why I don't like extrusion. The fasteners aren't terribly secure and can slide all over the place inside the t-slots. When you need to keep things in line or in certain spots, extrusion makes it harder.

While you can tension chain easily by sliding things around, those same things sliding around during a match can throw chains. I have first hand experience with that.

You don't need a different material, just a stronger arm on whoever installs the hardware and a little Lock-Tite too.
